IMPROVEMENT IN MACHINES FOR SIZING YARN.

Specification forming part of Letters Patent No. 134,964, dated January 21, 1873.

To all whom it may concern:

Be it known that I, THOMAS ABBOTT, of Blackburn, in the county of Lancaster, Kingdom of Great Britain and Ireland, have invented certain Improvements in Machinery Employed in Sizing Yarn, of which the following is a specification:

This invention relates to that part of sizingmachines which effects the marking of the yarns or warps; and consists, principally, of an arrangement of mechanism for resetting the marking apparatus after the completion and marking of a beam and before the commencement of another.

With the arrangement usually employed for that purpose it is necessary for the workman to leave the end of the machine, (where the beam is,) and after going to the side of the machine to make several turns of a handle to bring the marking-bowl back to its original position; and the object of myinvention is to enable the workman, without moving from his place at the end of the machine, to throw out of gear the wheel which actuates the marking apparatus, and by one turn of a handle placed within his reach to bring back the markingbowl and the index-plate to their original position.

In order to enable others skilled in the art to make and use my invention, I will nowproceed to describe its construction and operation.

On reference to the accompanying two sheets of drawing, which form part of this specification, Figure 1 is a longitudinal section of so much of the delivering-end of a sizing-machine as is necessary to illustrate my improvements, the latter being represented in side elevation. Fig. 2 is a plan or horizontal view of the same as seen from above. Fig. 3' is a section on an enlarged scale of the mechanism of the indexplate. Fig.4 is a plan view of an arrangement for dispensing with the long lever for moving the clutch-box. Fig. 5 is a similar view of a modification, working with three bevel-wheels and dispensing with the clutch-box; and Figs. (3 and 7 are side and front views of the mechanism for marking the yarn with solid ink.

In Figs. 1 and 2, a a is part of the framework of the machine; I) b is the yarn-beam, and c c the measuring-roller; the latter drives the longitudinal shaft d 61* by spur and worm gearing in the usual manner. I make the said shaft d 01*, however, in two parts, coupled together by the clutch-box e c, on sliding which out of gear by raising the leverhandle ff the part d can be disconnected from the part d*. The transverse shaft g g, which carries the marking-bowl h h and tumbler i i, is driven, as usual, by a pair of miter-wheels, 70 k. The marking-bowl runs upon an inking-roller, l l, which revolves in the ink in the trough m m, and thus distributes ink to the markingbowl. Upon the outer end of the part d of the longitudinal shaft is keyeda winch-handle, n n, which, (as well as the handle of the lever f f,) is Within easy reach of the workmans hand as he stands at the end of the machine,

so that when a beam is finished he can, withp out moving from his place at the end of the machine, first disconnect the part d of the longitudinal shaft from the part at by raising the handle of the lev'erf; and having done so he then, by giving one turn only to the handle a "(at the end of the part 61* of shaft) can bring the marking-bowl back to its original position. 7

1 would here observe that fixed upon the part (1* is a finger, 0 0, which, as the shaft revolves, comes against a projection, 12 p, on the lever j, which acts as a stop, so as to define the exact position of the marking-bowl. This only acts whenever the lever. is raised, and, consequently, the clutch-box e e is outof gear. At other times when the lever is down the finger does not reach it. The raising of gear with its driving mechanism, and allows a coiled spring to return the same to the zero point ready to commence measuring a fresh length.

()n referring to Fig. 3, f f is part of the lever which is provided with a pin, q q, working in an inclined slot, r, in a short lever, 8, attached to a slide, 25 t, which (when the lever f f is raised) draws the spur-pinion u out of gear with the wheel o, and allows the coiled spring to to turn the index-plate as back to zero. When the apparatus is thrown into gear again the revolution of the index-plate or dial winds up the spring ready for fresh action.

It will be evident that in cases where a fixed dial and a revolving index are used it is the teaser latter that will have to be thrown out of gear and returned to zero in a similar manner.

In the arrangement shown at Fig. at the long leverff is dispensed with. The boss of the miter-wheel k on the part 61* of the shaft slides on a key or feather, and has a neck enibraced by a fixed clip, which keeps it always in gear with the miter-wheel on the transverse shaft 9. The part 61* of the shaft is made to slide longitudinally, so as to throw the clutchbox e 0 into or out of gear, and when in gear is held in position by means of a clip, q. When this clip q is raised the workman can draw the shaft 01* in the direction of the arrow, so as to bring the clutch-box out of gear, and then turn the handle a back, as before described. The disk 19 draws back the slide 15 t and disengages the index-pinion, and atooth, 0, on the disk acts against a fixed stop, 1", to define the position of the marking bowl on starting a fresh beam, as before.

, In the arrangement shown at Fig. 5 the clutchbox is dispensed with, and three miterwheels are employed. The wheel 70* on the part 01* of the longitudinal shaft is always in gear with the miter-wheel on the end of the transverse shaft 9, but the boss of the wheel Icon the part at of the shaft slides on a key or feather, and has a neck or groove, embraced by a clip orv fork, on the end of the lever f f so that when the beam is finished the wheel is can be thrown out of gear, while the markingbowl is turned back by the handle a, as in the previously-described arrangements.

In the marking instrument itself, which is 1 illustrated by Figs. 6 and 7, I dispense with liquid or semi-fluid ink entirely, and form the bowl of a solid piece or block, a. a, of com the transverse shaft 9 a cam or wiper, h, which acts against a bowl, 6, attached to the lever is, which carries the marker a and in some cases I propose to carry the marker in a vertical slide instead of mounting it in the lever k.

Claims.

1. The shaft, consisting of two sections, d 01*, which may be connected or disconnected, substantially as described, in combination with marking apparatus operated by the section d*, which extends to the front of the machine, and is provided with a winch, a, or its equivalent.

2. The combination, with the lever ff, of the pin q, slot 1*, lever s, and slide t, Fig. 3, or other equivalent device, for returning the dial-plate or the index-finger to the zeropoint 011 adjusting the lever. V

3. The combination, with the shaft and lever f, of the finger 0 and stop, 19, or other equivalent device, for defining the position of the marking bowl or instrument at the commencement of a fresh beam.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

THOS. ABBOTT.
